Moscow – Leningrad, 1932, pp. 165 – 169[Introduction] The theory of probability is nearly the only branch of mathematics where,as also acknowledged abroad, even the pre-revolutionary Russian science from the time ofChebyshev had been occupying a leading position. The responsibility for the maintenance<strong>and</strong> strengthening of this leading part naturally lay on the <strong>Soviet</strong> mathematicians <strong>and</strong> becameeven greater <strong>and</strong> more honorable since, during the last 10 – 15 years, the European scientificthought in the sphere of probability theory (Italy is here on the first place, then come theSc<strong>and</strong>inavian countries, Germany <strong>and</strong> France) considerably advanced from its infantile stage<strong>and</strong> rapidly attained the level established in Russia by the contribution of Chebyshev,Markov <strong>and</strong> Liapunov. The foremost European schools at least qualitatively even exceededthat level by coming out at once on the wide road provided by the modern methods ofmathematical analysis <strong>and</strong> free from the touch of provincialism from which (in spite of thegreatness of its separate findings) our pre-revolutionary scientific school neverthelesssuffered.It seems that now, after 15 years of work 1 , we, <strong>Soviet</strong> mathematicians, may state that wehave with credit accomplished the goal that had historically fallen to our lot. Notwithst<strong>and</strong>ingthe already mentioned very considerable advances of the West-European scientific thought,today also the <strong>Soviet</strong> probability theory is occupying the first place if not in accord with thenumber of publications, but in any case by their basic role <strong>and</strong> scientific level. The present-
day portrait of this discipline has no features, nor has its workshop a single range of problemswhose origin was not initiated by <strong>Soviet</strong> mathematics. And the level of our science is bestdescribed by noting that European mathematicians are until now discovering laws known to,<strong>and</strong> published by us already five – ten years ago; <strong>and</strong> that they (sometimes includingscientists of the very first rank) publish results which were long ago introduced into ourlectures <strong>and</strong> seminars <strong>and</strong> which we have never made public only because of consideringthem shallow <strong>and</strong> immature if not altogether trivial.It is interesting to note that after the October upheaval 2 our probability theory underwent aconsiderable geographical shift. In former times, it was chiefly cultivated in Leningrad {inPetersburg/Petrograd} but during these 15 years Leningrad {Petrograd until 1924} did notoffer any considerable achievements. The main school was created in Moscow (Khinchin,Kolmogorov, Glivenko, Smirnov, Slutsky) <strong>and</strong> very substantial findings were made inKharkov (Bernstein) <strong>and</strong> Tashkent (Romanovsky).Before proceeding to our brief essay on those lines of development of the theory ofprobability which we consider most important, we ought to warn our readers that it is not ourgoal to provide even an incomplete list of <strong>Soviet</strong> accomplishments in this sphere; we aim attracing the main issues which occupied our scientists <strong>and</strong> at indicating the essence which wecontributed to the international development of our science, but we do not claim anycomprehensiveness here. Then, we ought to add a reservation to the effect that we restrict ourdescription to those lines of investigation which have purely theoretical importance, <strong>and</strong> weleave completely aside all research in the field of practical statistics <strong>and</strong> other applications ofprobability in which <strong>Soviet</strong> science may also take pride. We consider the following issues ashaving been basic for the development of the <strong>Soviet</strong> theory of probability.1. Investigations connected with the so-called limit theorem of the theory of probability,i.e., with the justification of the Gauss law as the limiting distribution for normed sums ofr<strong>and</strong>om variables. Formerly, almost exclusively considered were the one-dimensional case<strong>and</strong> series of mutually independent r<strong>and</strong>om variables. Nowadays we are able to extend thelimit theorem, on the one h<strong>and</strong>, to the many-dimensional case, <strong>and</strong>, on the other h<strong>and</strong>, toseries of mutually dependent variables. <strong>Soviet</strong> mathematicians <strong>and</strong> Bernstein in the first placeboth initiated these generalizations <strong>and</strong> achieved the most important discoveries {here}.Bernstein accomplished fundamental results in both directions; Kolmogorov arrived at someextensions; Khinchin justified normal correlation by the direct Lindeberg method. Thissphere of issues met with a most lively response in the European literature <strong>and</strong> continues tobe developed both at home <strong>and</strong> abroad.2. For a long time now, the theory of functions of a real variable, that was worked out atthe beginning of our {of the 20 th } century, compelled mathematicians to feel a number ofdeep similarities connecting the stochastic concepts <strong>and</strong> methods with the main notions of themetric theory of sets <strong>and</strong> functions. The appropriate process of modernizing the methodologyof probability theory, its notation <strong>and</strong> terminology, is one of the most important aspects ofthe modern issues of our scientific domain. This process is far from being completed, but wealready feel with complete definiteness how much it is offering to probability theory, – howmuch its development fosters the unity <strong>and</strong> the clarity of the scientific method, the harmony<strong>and</strong> the visibility of the scientific building itself. With respect to their level, even the mostpowerful stochastic schools (for example, the Italian school) insufficiently mastering themethods of the function theory become noticeably lower than those (the French, the Moscowschool) where these methods are entrenched. It is therefore quite natural that Moscowmathematicians, most of whom had developed in the Luzin school, have marched in the frontline of this movement. Slutsky should be named here in the first instance, then Glivenko <strong>and</strong>Kolmogorov. In particular, the last-mentioned had revealed, with exhausting depth <strong>and</strong>
